As a child [primary school], every early summer, just outside the school's gate, the 'sugarcane-man' would set up, selling short sections of sugarcane... he'd peel the tough outer layer for us with a very sharp knife and we'd walk away happily chewing and sucking on the exposed cane.

I'd imagine that just like honey was an occasional and/or seasonal paleo treat ,so would have been raw sugarcane for those paleo people living where sugarcane was a native plant... tropical South Asia and Southeast Asia.

No doubt it's the refined, ubiquitous stuff, consumed in disproportionate huge quantities, that paleo people weren't exposed to.
